Solar Cooling Bottle/ Water Bottle

The Solar Cooling Bottle is able to cool the water saved inside by employing the natural phenomenon of evaporation. On a summer day when the evaporation is fostered by the higher temperature, there is a heat subtraction that causes paradox, a drop in temperature of the water saved in the bottle. This happens because of a fiber that wraps the aluminum bottle. It’s moisten by water and is in contact with air stream in order to facilitate the evaporation. The bottle is effortless to use. It’s completely disassembled. All you need to do is unscrew the upper and lower supports, moisten the rayon sheet, fill the bottle and put it all back together
